Heavy-Duty Truck Engine Sealing System
A leading European truck manufacturer required a complete EPDM gasket set for their new Euro 7 engine platform. Operating temperature: -40°C to 150°C, continuous exposure to synthetic engine oil.
- Challenge: Tolerances of ±0.05mm across 8 gasket variants
- Solution: Custom EPDM compound with enhanced oil resistance
- Result: 200,000+ units delivered, zero field failures, 18% cost savings vs. previous supplier
Saltwater-Resistant Dock Fender System
A Southeast Asian port authority needed heavy-duty rubber fenders for a new deep-water berth. Exposure: continuous saltwater immersion, UV radiation, and impact from 100,000 DWT vessels.
- Challenge: Withstand 500+ kN impact force in saltwater environment
- Solution: CR/EPDM blend with UV stabilizers and carbon black reinforcement
- Result: 5-year service life validated, 30% longer replacement interval than specification
FDA-Compliant Silicone Gaskets for Bottling Line
A North American beverage company required FDA 21 CFR 177.2600 compliant silicone gaskets for their high-speed filling line. Contact with food products, CIP cleaning chemicals at 85°C.
- Challenge: FDA compliance plus chemical resistance to aggressive CIP solutions
- Solution: Platinum-cured VMQ silicone, post-cured for low extractables
- Result: 500,000 gaskets annually, full FDA/USP Class VI compliance, zero contamination incidents
Seismic Isolation Bearings for Bridge Project
A Middle Eastern infrastructure project required high-damping rubber bearings for a 2.4km bridge in a seismic zone. Design life: 50 years with minimal maintenance.
